Fouts, SLAC 4 I&T/Online Progress  LICOS released and installed on the MCR .dbx (as opposed to LCAT) based C&T DB – Solves command enumerations problem  AlarmHandler update to allow sensitivity to configuration  Well tested against test bed, but: – No trial run against the LAT yet  Bent pipe updates  Telemetry redaction is now.dbx based  Warns operators of NAKs and disconnects  Preparing configurations for compatibility with FSW B  Configuration tool development (Populates MOOT DB)  LPA configurations built (still need verification)  Handling of APIDs other than LPA, LCI and M7 from SSR  Working TDFAnalysis issues (OSYS-143)  MCR maintenance  Various JIRAed bug fixes

GLAST LAT Instrument GLAST Monthly Mission Review May 2, 2007 K.A. Fouts, SLAC 7 LAT Mechanical Ops prior to EMI  LAT alignments need to be complete since the LAT reflector ball locations are covered up by the LAT MLI.  GD needs to asses how many of these locations are required for interim alignment checks to minimize blanket removal each time)  Re-route LAT test instrumentation wiring, tie down & put ends inside an EMI (conductive material) bag  Re-route chiller lines (install 90 degree unions) to exit LAT MLI in a way that we can seal around for EMI testing  Install patches on inside X-side blankets (per existing NCR)  Close-out & tape LAT MLI.

GLAST LAT Instrument GLAST Monthly Mission Review May 2, 2007 K.A. Fouts, SLAC 8 LAT Issues and Concerns  Observatory command and telemetry dropouts  Reviewing command and telemetry logs for additional supporting data.  Responding to requests from GD for specific information related to known events.  LAT SE will continue to support GD when requested.  LAT Test Time  Additional LAT test time availability during EMI testing – LICOS trial run against the S/C + LAT – Install B – Rerun Calibration runs  Observatory Schedule  LAT MLI closeout for EMI  Flight installation of LAT Radiators  RS103 levels of 150V/M  Tests/analysis at CKC of the circuit at 80V/M show minimal risk
